I've tested this on both DNN 6.2.9 and 7.2.2.
In ListX, the "Records per Page" control retained it's setting. In other words, if I set it to show 250 Records per Page it would continue to do so even after a page refresh or post back.
Now that I'm upgrading ListX Modules to OWS I find that they no longer hold their setting.
Can this be changed or fixed?
